11-15 Duramax DPF Delete Pipe without muffler by Mel’s Manufacturing is an ideal solution to pair with a race tuner and delete your Cat and diesel particulate filter (DPF) off your diesel pickup truck. You must use a tuner when removing the DPF off of the vehicle.

This is a DPF Delete Pipe only, not a full Exhaust Kit.

This pipe is the V Band Flange. If you have the 3-Bolt Style please order the 15.5-16 pipe here. You can see which type of flange you have by looking at the downpipe through the passenger wheel well.
